Roller Skates

Read the story and answer the questions to test your comprehension.

The first roller skate design was introduced in 1760, but the four wheels of the skate couldn't move, so it was hard for a skater to turn. Another design, called the "rocking skate" came along in 1863 and fixed the problem. Since then, roller skates have been used in every age since, especially in the 1970's, when people did roller derbys and hung out at the skating rink, dancing along to disco music.
